it is not necessary to work with an array of a spline object. It is important to make a controlled animation of the sequential unscrewing of the bolts of the nuts ... as I understand it, this can only be done with a list object and xpresso...
This is my scene. I want to do the subsequent untwisting of the bolt-nut pair. removal of covers, disconnection of the gearbox, etc. and then collect it back.

Thank you for your attention JED. But i need to control start, duration, speed animation.
I want to make a spaced screw conveyor. It will include nuts and washer also. Can you help me?
